Ceiling system and panel-securing device therefor

Claim 3

A device as defined in claim 1, wherein the carrier member includes a pair of seat portions respectively grippable between the side flanges of the panel at locations spaced along the length of the panel, for preventing angular displacement of the carrier member relative to the panel.

Claim 4

A device as defined in claim 2, wherein said carrier member further includes a web having said seat portions respectively disposed at opposite ends thereof and defining a circular hole disposed equidistantly from said seat portions, and wherein said hanger member comprises a lower portion having opposed laterally extending legs for engaging said web from below at spaced locations outwardly of said hole and an upper portion projecting upwardly from said legs for extending upwardly through said hole to engage the stringer above said carrier member while permitting unobstructed rotation of said carrier member relative to said hanger member about said vertical axis.

Claim 5

A device as defined in claim 3, wherein said hanger member legs are resiliently deformable and are shaped and positioned to press said web upwardly against the stringer when the hanger member is mounted on the stringer.

Claim 6

A device as defined in claim 3 or 4, for use with a stringer of inverted-T profile with opposed longitudinal flanges, wherein said upper portion of said hanger member comprises a pair of resiliently deformable arms for respectively hooking over the longitudinal flanges of the stringer and gripping the stringer between them along horizontally extended lines of contact.

Claim 7

A device as defined in claim 3 or 4, wherein said upper portion of said hanger member comprises a downwardly opening yoke for overlying the stringer in engagement therewith along opposed horizontally extended contact regions.

Claim 8

In a ceiling system, in combination, (a) at least two horizontally elongated stringers spaced apart at a common level; (b) at least one horizontally elongated ceiling panel of upwardly opening C-shaped profile with resiliently deformable side flanges, extending beneath and transversely of said stringers; and (c) a plurality of devices, respectively mounted on said stringers for securing said one panel to said stringers, each said device comprising (i) a carrier member gripped between the side flanges of said one panel in a fixed angular position relative thereto; and (ii) a hanger member, mounted on one of the stringers in a fixed angular position relative thereto, for supporting the carrier member beneath the last-mentioned stringer for unobstructed rotation relative to the last-mentioned stringer about a vertical axis, such that the panel is suspended from the stringer.

Claim 9

In a ceiling system, in combination, (a) at least two horizontally elongated stringers spaced apart at a common level; (b) at least one horizontally elongated ceiling panel of upwardly opening C-shaped profile with resiliently deformable side flanges, extending beneath and transversely of said stringers; and (c) a plurality of devices, respectively mounted on said stringers for securing said one panel to said stringers, each said device comprising (i) a carrier member gripped between the side flanges of said one panel in a fixed angular position relative thereto; and (ii) a hanger member, mounted on one of the stringers in a fixed angular position relative thereto, for supporting the carrier member beneath the last-mentioned stringer for unobstructed rotation relative to the last-mentioned stringer about a vertical axis, such that the panel is suspended from the stringer.

Claim 10

A system as defined in claim 7, wherein said stringers are parallel to each other and said one panel is oriented at an oblique angle to the stringers as viewed in plan projection.
